随着城市化进程的加快,新农村建设和城市管网改造的推进,塑料管道的需求会越来越大,塑料管道产业迎来了发展的春天。以前,传统的城市排水排污管道一般采用水泥管或者钢筋混凝土管道,也有使用钢管、铸铁管等金属管道的,这些类型的管道一般比较笨重,造价高,而且使用的寿命也不是很长。而塑料管道具有节能、节水、节地、节材等特点,塑料管道生产能耗低,仅为钢管和铸铁管的30%～50%。塑料管道管 With the acceleration of urbanization, the advancement of new rural construction and urban pipe network renovation, the demand for plastic pipes will increase, and the plastic pipe industry will usher in the spring of development. In the past, traditional urban drainage and sewage pipes generally used cement pipes or reinforced concrete pipes, and also used metal pipes such as steel pipes and cast iron pipes. These types of pipes were generally heavy and expensive, and the service life was not long. The plastic pipe has the characteristics of energy saving, water saving, land saving, and material saving. The energy consumption of the plastic pipe is low, which is only 30% to 50% of the steel pipe and cast iron pipe. Plastic pipe
